  • Exercise compliance apparatus and method
    Patent number: 5626537
    Abstract: A device adapted to be placed upon a human for the purpose of counting exercises incident to therapeutically treating and restoring the part of the anatomy being exercised to normal use. The device accurately counts the number of repetitions the part of the anatomy is exercised in a given time period. The accuracy of the total number in a given time period is assured by anti-cheating elements which render the counting mechanism inoperable in the event the device is not on the human anatomy when the device is utilized.

  • Visually keyed connector and plug assemblies
    Patent number: 5417585
    Abstract: Visually keyed connector (10) and plug assemblies (36) wherein the insulative housings (16,38) are formed of material of the same color only when the number and configuration of the terminal receiving cavities (22) of the connector and the contacts (42) of the plug have mating compatibility. The connector and plug assemblies have their mating faces (20,40) exposed to provide a visual indication of such compatibility.
